Diagnostic role of NLR, MLR and PLR in patients with lipoma and liposarcoma

Abstract

Aim: The aim of this study is to investigate the diagnostic role of Neutrophil-to-lymphocyte ratio (NLR), Monocyte-to-lymphocyte ratio (MLR) and Platelet-to-lymphocyte ratio (PLR) in patients with lipoma and liposarcoma.
 
 Material and Methods: Patients operated for lipoma and liposarcoma at our institution between 2015 and 2019 were included in this retrospective study. A total of 92 patients with 44 lipoma and 48 liposarcoma were included in this study. The results of the complete blood count before treatment were retrospectively analyzed. 94 patients with complete blood count results admitted to the same center for reasons other than fracture, infection or tumors with similar age and sex to the aforementioned study group were included as healthy controls.
 
 Results: The average age of lipoma, liposarcoma and control groups included in the study was 55.3 ± 11.6, 48.9 ± 14.7 and 52.1 ± 11.7, respectively. While 50% of lipomas are located on the thigh and 40.9% are on the shoulder, 72.9% of the liposarcomas are located on the thigh. NLR values of the liposarcoma group were significantly higher than the control group. It was observed that PLR values did not differ significantly between groups. It was noted that MLR values were statistically significantly higher in the liposarcoma group than in the lipoma group. A significant but weak AUC value (AUC = 0.620, p = 0.020) was obtained for NLR. When the cut-off value and sensitivity, specificity, + LHR, PPV and NPV values of these cut off values are examined, NLR 1.83 and above values; It pointed out that his predictability was poor in the diagnostic approach for liposarcoma.
 
 Conclusion: Consequently, lipoma and liposarcoma are the most common forms of benign and malignant soft tissue tumors. NLR and MLR may be valuable in the diagnosis of liposarcoma, but more studies are needed in this regard.
